DISEASES OF THE PENIS AND PREPUCE. 

 Phimosis and Paraphimosis. 



By phimosis we mean a contraction of the prepuce over the free 

 ■end of the penis. It is often of congenital origin, and is fre- 

 quently caused by injuries and consequent inflammatory swell- 

 ings; but as the foreskin is rarely withdrawn in the dog it is of 

 little importance, for as soon as the penis passes through the nar- 

 row opening of the prepuce during coitus or from erection the 

 prepuce becomes tightened behind the glans penis and causes what 

 is termed paraphimosis; the narrow ring of the prepuce causes 

 venous stagnation and a swelling and purple coloration of the 

 glans, and, if this is allowed to remain some time, causes partial 

 gangrene. 



The therapeutics of paraphimosis consists in reducing the glans 

 as soon as possible with friction and careful manipulation; this is 

 accomplished by careful lubricating of the parts with some bland 

 oil and putting a steady pressure on the glans, at the same time 

 pressing forward the prepuce over the enlarged part; with a little 

 patience it is reduced. If this is not successful, bathe the glans 

 with cold water or alum applications. If we do not reduce it by 

 this means, then cut the ring with a probe-pointed bistoury or a 

 pair of scissors. The last means will reduce it immediately. It 

 is well, however, not to resort to this until you have tried every 

 other method. 



Gonorrhoea — Gonorrhcea of the Prepuce. 



By this term we mean the catarrhal inflammation of the skin of 

 the prepuce, which is similar to mucous membrane. It is prob- 

 ably caused by retention of urine, dirt, uncleanliness, or mastur- 

 bation; it is frequently observed in old dogs, with stagnation of 

 the veins of the prostate (Siedamgrotzky). The symptoms con- 

 sist in slight redness, swelling of the prepuce and glans, and the 

 secretion of a thin, purulent mucus, which is generally licked off 

 by the animal. The lymph-follicles are generally swollen, and. 

 can be felt by manipulation with the finger as small bodies about 

 the size of a seed or pea. The treatment consists in the injeciion
